Believe it or not, Stephen Colbert is a giant nerd with a literal trove of pop-culture knowledge.
He's an authority on Middle-Earth and regularly schools fools (celebrities) on Tolkien lore, like that time he took on James Franco in a trivia-off.
Here, Colbert adds his weight of truthiness to proceedings and analyses the new lightsaber from The Force Awakens trailer.
Solid logic, Colbert. We'd corroborate everything he's saying here, especially about the plasma streams.
